1. The problem is to design a bar graph depicting gene frequencies for dominant and recessive traits based on the given data. 2. The traits and their frequencies are: - Hair above knuckles: 62.5% dominant, 37.5% recessive - Unattached earlobes: 75% dominant, 25% recessive - Widow's peak: 16.6\overline{6}% dominant, 83.3\overline{3}% recessive - Can roll tongue: 87.5% dominant, 12.5% recessive - Ability to taste P.T.C.: unknown frequencies 3. Since the Ability to taste P.T.C. frequencies are unknown, we cannot plot them accurately. 4. The x-axis will be labeled with each trait pair. 5. The y-axis will represent frequency percentages from 0 to 100. 6. Bars will be drawn with heights corresponding to the frequencies given. 7. The graph will have vertical bars for each dominant and recessive trait side by side for comparison. Final answer: A bar graph template with labeled axes and bars representing the frequencies above, except for the unknown P.T.C. trait frequencies which are omitted due to missing data.
